  • Rotary connector and connecting structure of flexible cable and lead block used therein
    Patent number: 6435885
    Abstract: A flexible cable is constructed in a band-like shape by sandwiching a plurality of conductive wires with a pair of insulating films, and a lead block is constructed by fixing a plurality of joint bars to a resin body. In a connecting structure of the flexible cable and the lead block, a part of one of the insulating films is removed so that the conductive wires are exposed at an end of the flexible cable. In addition, through holes for preventing deformation are formed in the remaining insulating film at positions between the exposed parts of the conductive wires. The exposed parts of the conductive wires are connected to the joint bars at positions close to the through holes by ultrasonic welding.
    Type: Grant

  • Connection structure of flat cable to terminals
    Patent number: 5962813
    Abstract: In a connection structure of a flat cable to terminals of the present invention, the conductors held by the back film of the flat cable are ultrasonic welded to the terminals of an external part. In this arrangement, even if the conductors are formed to a very thin thickness, since they are neither twisted nor separated from each other, solid-state welding can be made to target positions.
